Sartorius Signum 1 Operating Instruction page 69

Minimum Load
The minimum load for the first class is
configured in the operating menu,
under:
Appl 2 :
class : 3.6.
Once the limit is exceeded by the load,
initialization can begin.
Once the application is initialized,
a weight value below the minimum
load is designated Class 0; no class
is displayed.
The minimum load required for auto-
matic taring of the container weight
on the platform ("autotare first
weight"), or for automatic printout of
results, is configured in the operating
menu, under:
Appl : m.weigh : 3.5.
You can choose from the following
10 levels for this setting:
1 digit
2 digits
5 digits
10 digits
20 digits
50 digits
100 digits
200 digits
500 digits
1000 digits
The "digits" here refer to the scale
intervals in the connected weighing
platform. If the interval of the
connected platform is 1 g, for example,
and 1000 digits are required, you must
place at least 1000 g (=1000 intervals
=1000 digits) on the weighing platform
for the first class to activate autotaring
or autoprint.
Display
The result of a given measurement
is shown as either a weight value or
the class number.
– Weight display
The current weight is shown in the
measured value line and the current
class in the text line.
– Display of classes
The current class is shown in the
measured value line, and the current
weight in the text line.
Digital Input/Output Interface
The Classification application supports
the digital input/output-interface.
There are 4 control lines, or outputs,
which are activated as follows
(see also the diagram on the right):
– With 3 classes:
– Class 1
– Class 2
– Class 3
– Set
– With 5 classes:
– Classes 1/2
– Classes 2/3/4
– Classes 4/5
– Set
In the operating menu, under:
Appl 2 :
class : 4.7.
you can define whether these control
ports are
– off,
– always on,
– activated at stability,
The "SET" output normally changes
its voltage level when the current weight
exceeds the minimum load. Alternatively,
you can assign the "Operative" function
(indicating "Ready-for-use") to this port.
